The opening shown in this picture, protected by plastic, is part of the path that will lead from Headquarters to the ITER Control Building. Once extended, the tunnel will take operators to the basement level of the Control Building, from where stairs or a lift will lead to the Main Control Room. Under the room's high ceiling (7 metres), work stations for some 100 operators, engineers and researchers are planned. A glass-walled viewing gallery will offer visitors a panoramic view ... and a sense of what it is like to work at harnessing the energy of the stars.
